The elements in the regular table are not stable except the noble gases. Therefore, elements shot to reaction with various other elements, to gain the noble gas electron configuration to attain stability. Likewise, sodium additionally has to obtain an electron to attain the electron construction of the noble gas, Neon. All nonmetals react v sodium developing sodium ions. Except some similarities, salt atom and also sodium ion has various physical and chemical properties as result of the readjust of one electron.

Sodium Atom

Sodium, i beg your pardon symbolized together Na is a team 1 aspect with the atomic number 11. Sodium has properties the a team 1 metal. The atomic load of the is 22.989. That electron configuration is 1s2 2s2 2p6 3s1. Salt is the very first element in the 3rd period, for this reason the electrons have actually started to fill right into orbital 3. Salt exists together a silvery shade solid. But sodium reacts very rapidly v oxygen as soon as it is exposed to air, thus makes an oxide coating in dull color. Salt is soft sufficient to cut by a knife, and also as shortly as that cuts, the silvery shade disappears because of the oxide layer formation. Thickness of sodium is reduced than the of water, so the floats in water while strongly reacting. Sodium offers a brilliant yellow flame when burns in the air. Boiling suggest of sodium is 883 °C, and the melting point is 97.72 °C. Salt has countless isotopes. Amongst them, Na-23 is most abundant v the family member abundance of around 99%. Salt is crucial element in living equipment to preserve osmotic balance, for nerve advertise transmission and also so on. Salt is additionally used come synthesize assorted other chemicals, organic compounds, soap and also for salt vapor lamps.

Sodium Ion

When salt atom release its valence electron to another atom, it creates a monovalent (+1) cation. It has actually an electronic configuration that 1s2 2s2 2p6, i m sorry is similar to the electronic configuration of neon. Removal of an electron indigenous this is hard; therefore, the ionization energy is really high (4562 kJ·mol−1). Electronegativity of salt is an extremely low (according come the Pauling’s range it is around 0.93), permitting it to form cations through donating one electron come a greater electronegative atom (like halogens). Therefore, sodium regularly makes ionic compounds.


What is the difference in between Sodium Atom and Sodium Ion?

• Sodium ion has derived a stable digital configuration by offering out one electron native the salt atom. Therefore, salt ion has one electron much less than the salt ion.

• In various other words, the valence shell/ last shell of salt atom has actually only one electron. Yet in sodium ion the critical shell has 8 electrons.

• Sodium ion has actually a +1 charge whereas salt atom is neutral.

• Sodium atom is an extremely reactive; therefore, i will not ~ find totally free in nature. The exists as sodium ions in a compound.

• Because the the release of one electron, the sodium ion radius differs from the atomic radius.

• Sodium ion is attracted to negatively charged electrodes, yet sodium atom is not.

• The very first ionization power of sodium atom is an extremely low contrasted to the ionization power of sodium +1 ion.
